Improvement in marine grain-vessels



PATENT WILLIAM INGLIS, OF BOLTON, ENGLAND, AND JAMES INGLIS, OFMONTREAL, CANADA.

IMPROVEMENT IN MARINE GRAIN-VESSELS.

Specification forming part of Letters Patent No. l 62,074, dated April13, 1875; application tiled January 9, 1875.

To all whom it may concern:

Be it known that we, WILLIAM INGLIs, of the town of Bolton, in thecounty of Lancaster, England, mechanical engineer, and JAMES INGLIS, ofthe city of Montreal, Province ot' Quebec, Canada, merchant, haveinvented certain new and useful Improvements on Floating Vessels forStoring Grain; and We do hereby declare that the following is a full,clear, and exact description ot' the same.

This invention relates to boats or vessels for storing, lightering, orcarrying grain, and has for its object, by certain improvements in form,construction, and arrangement, to render such boat or vessel lesscostly, and less liable to strains due to the load carried, than boatsor vessels of the ordinary construction.

In the improved vessels or boats, one or more floating tanks or bins areused, inclosed or surrounded by a separate boat or raft. The tanks orbins may be cylindrical, rectangular, or other desired regular form; butWhere a number of them are used together in one raft, &c., We prefer tomake the end tanks or bins cylindrical, semicylindrical, or triangular,While the inner ones will be rectangular. This is for the purpose ofgaining as good general Water-line as possible to the combined set ot'tanks or bins; otherwise they may be made any desired shape, and arepreferably made of iron plates.

The oating tanks are constructed with inner bottoms made of any suitablematerial, and separate from the outer ones, but provided With a suitablearrangement of supports. The inner bottom is made to slope on all sidestoward the center, so that when the tank is being emptied, the grain maytend to ow toward the center and bottom Without shovelin g, from whichpoint it can be elevated in the usual Way.

In the drawings hereunto annexed, similar letters of reference indicatelike parts, and Figure lis a sectional elevation embodying ourinvention. Fig. 2- is a side elevation ot' combined tanks, &c. Fig. 3 isa plan of Fig. 2.

Letters A are tanks or bins 5 B, the lower or outer bottom; C, the innerbottom, inclined toward the center. The top of the heating bin is shownpartially covered or decked over, having an opening, D, Which may betted With a movable covering, or otherwise protected. E is the separateboat or raft, a portion only being shown in Fig. l. Figs. 2 and 3 showan elevation and plan of a vessel composed of iive of the oating bins A,inclosed by the separate boat or rait E. The two outer tanks are shownas cylindrical; but they may be made With their outer haltsemicylindrical, and their inner rectangular, or they may be constructedof triangular form, situated to have an angle outward, and one sideparallel to the side of the adjacent inner bin. When loaded, the tanks Asink independently ot' each other, and separate from the raft or boat E,so that whatever may be the load carried by the tanks or bins A, thedraft of the separate protecting boat or rat't E is notchanged.

When the tanks or bins lare loaded with wheat or heavy grain, thepressure ofthe grain on the inside will, to a great extent, balance thatof the water on the outside of the vessels, so that tanks made ot'comparatively thin plates will suit for carrying heavy loads.

Having described the invention, and how the same is carried into effect,we beg to state that we do not restrict ourselves to the precise detailsdescribed but What We claim is as follows:

In combination with the boat or ratt E, the disconnected andindependently-floating tanks or bins A, held separated, so that theimmersed portion of each will be surrounded by Wateron all sides,substantially as and for the purpose specilied.
